Lhao Vo (Burmese: လော်ဝေါ်,) also known as Maru (မရူ) and Langsu (Chinese: 浪速), is a Burmish language spoken in Burma and by a few thousand speakers in China.
Dai Qingxia (2005:3) reports 5,600 Langsu speakers in China. Many thousands more are dispersed across the eastern edge of Kachin State, Myanmar.
The Langsu people call themselves lɔ̃˧˩ vɔ˧˩ (Chinese: Lang'e 浪峨)
The standard Lhaovo dialect is that of the Dago’ (tăkoʔ) hill area, on the east side of N'Mai River valley in Kachin State.
Sawada (2017) lists the following patois (subvarieties) of Lhaovo.
The Langsong (浪宋) are found in Zaoyang (早阳) in Yunlong County (in the Chinese province of Yunnan) as well as in Baocun (表村), Laomo (老末), and Sancha (三岔). They reportedly speak a highly endangered language that may be possibly related to Langsu.
